Definitions
- the present invention relates to a device for rolling up/rolling down a shade, comprising a frame construction with an upper stationary fastening for said shade and a rotatable tube that is movable in said frame construction to and from said fastening, for the purpose of taking up/letting down shading, and a drive with drive motor for rotation of said tube, and guide means for moving said tube.
- Such a device is known from EP 066560 Al. Shades are used in glasshouses and the like for screening against sunlight, for heat insulation, or for other purposes, immovably fastened, hanging vertically, to the frame construction of the glasshouse, and rolled up from the bottom by winding around a tube.
- these tubes have a relatively large diameter, and one or more tube motors are fitted in them.
- Such tubes can have great lengths, ranging from tens of metres to over one hundred metres.
- the tubes are guided in a guide with provision for transmission of power for the tube motors. When the motors are operated, the tubes move up and down relative to the guides.
- the tube motors have a relatively very limited service life, owing to their complex construction. There is certainly no question of durability and reliability in the present system, and repairs and failure to function properly not only cause irritation, but also involve high costs. Furthermore, the power supply cables moving along at the same time are susceptible to damage. Moreover, it is generally not possible to cover the wall of a glasshouse with a single screen, since horizontal trusses (girders) are present near the wall of the glasshouse, and because every effort is being made to utilize as much of the surface area of the glasshouse as possible, it is not permitted to fit the screen at some distance from the outside of the wall. Screens are consequently always fitted between the horizontal trusses in the wall of a glasshouse.
- This object is with the device described above in that said drive motor is rigidly connected to said frame, a drive shaft that can be rotated by said drive motor is present between said drive motor and said tube, and that a transmission device connected to said tube, movable on said frame in the direction of its axis and not rotatable relative to said drive shaft, is present, in order to transmit the rotary movement of said drive shaft to said tube.
- a simple motor that is immovably connected to the frame is used.
- a drive shaft which will be fitted vertically in the case of vertically moving shading.
- the transmission device described above moves up or down in the vertical direction along this drive shaft. This vertical movement is imposed by the rolling up or rolling down of shading on the tube connected to the transmission device.
- the tube preferably extends in a direction perpendicular to the drive shaft.
- a clutch that is effective when there is overloading i.e. an adjustable clutch
- the clutch becomes active, with the result that moment-limited disconnection of the roller tube relative to the drive shaft occurs.
- a braking feature in the drive line in combination with the adjustable slip-action clutch it is ensured that in the rolled-up position or in an intermediate position the roll-up tube does not roll out in an uncontrolled manner.
- Such a braking feature can be achieved with a worm wheel, for example, in the transmission device.
- the device described above for rolling up and rolling down shades can also be used in the case of a so-called twin screen, i.e. a tube on which two shades are rolled on top of each other.
- twin screen i.e. a tube on which two shades are rolled on top of each other.
- One of these shades is connected in the manner described above to an immovable fastening situated above it, while the other shade has a weighted free end and extends hanging downwards.
- the invention also relates to an assembly comprising a number of devices of the type described above, which devices are moved by means of a common drive shaft.
- a number of devices for example situated one above the other, by means of one drive shaft.
- this invention it is also possible to operate simultaneously by means of one drive shaft several devices that are situated one above the other and differ in terms of height and/or required torque. These devices may be situated between horizontal trusses of, for example, a glasshouse.
- the clutch described above and operating means to be fitted for it, such as stops it is possible during rotation of the drive shaft to make each transmission device, and consequently each screen, perform exactly the right movement, without overloading occurring. This means that a large number of tubes on which shading is wound can be operated by means of a single motor.
- At least one further drive shaft can be operated by means of the single motor. It is possible to operate not only vertically moving screens, but also horizontally fitted screens in this way. In this case the tube on which the shade is wound is kept taut by means of counterweights or another (spring) mechanism. It is possible to operate simultaneously with one drive motor not only horizontal screens, but also vertical screens or screens placed at an angle.
- Fig. 1 shows diagrammatically in elevation a part of a glasshouse construction provided with the assembly according to the invention
- Fig. 2 shows a detail of the transmission device according to Fig. 1;
- Fig. 3 shows a cross section along the line III-III in Fig. 2;
- Fig. 4 shows a variant of the screen according to the invention illustrated diagrammatically.
- Fig. 1 the assembly according to the present invention is indicated in its entirety by 1.
- the frame of the glasshouse is shown diagrammatically by 2. It is easily possible to use a separate frame for the construction according to the invention, but in the case of a glasshouse this was not found to be necessary.
- a motor 3 is immovably fastened to the frame construction 2.
- the auxiliary shaft 4 is present, and a substantially vertically extending drive shaft 6 is driven by way of a right-angled transmission 5.
- the drive shaft 6 extends through transmission devices 7 and 8 respectively, by means of which tubes 9 and 10 respectively are driven, for the purpose of moving screens 11 and 12 respectively. Stops 13 and 14, which can interact with the operating means 25 and 26 respectively shown in Fig. 2, are present.
- Fig. 1 The abovementioned screens 11 and 12 are illustrated in Fig. 1 by a solid line to the right of the vertical section 28. It will be understood that screens may also be present to the left of said section, as partially shown.
- transmission devices 7 and 8 Details of the transmission devices 7 and 8 respectively are shown in Figures 2 and 3. It can be seen from these figures that shaft 6 is provided with a groove 15 extending along its entire length.
- the transmission device is composed of a box 17, which by way of a guide 29 (see Fig. 3) can be slid along its own drive (shaft 6) and the vertical T-section 28 of the frame construction 2. If the output shaft of the transmission device is rigidly connected to either tube 9 or 10, the guidance described above can be omitted. If the structure and more particular the shaft 6 is not positioned vertically, also at the lower end thereof a bearing should be provided to maintain the non vertical position.
- a self-braking gear transmission 30, 31 which drives shaft 19, which in turn is connected to tube 10 (or 9).
- This self braking property can alternatively be provided in the drive motor, a possible reduction thereof or the right-angled transmission 5.
- a simple single gear transmission has been shown in box 17.
- An example is a planet-sun wheel system.
- the tubes 9 and 10 are (in the horizontal plane) on a substantial distance from the vertical drive shaft 6. This makes it possible to provide the structure shown in the figures and more particular the tubes 9 and 10 and the related screen to be positioned between the horizontal trusses of the frame structure resulting in a surface saving.
- a sleeve 21 is provided, which, as can be seen from Fig. 3, is provided with a key-shaped projection 18, which means that sleeve 21 is not rotatable, but is slidable, relative to drive shaft 6.
- Sleeve 21 is provided with a(n) (adjustable) slip-action clutch 23, fitted corresponding to tooth system 24 on gear sleeve 16.
- tooth system 23 is driven to tooth system 24, so that the rotary movement applied to sleeve 21 can be transmitted to gear sleeve 16. If, however, the load is too great, tooth systems 23 and 24 will move past each other and slip will occur.
- the moment of slip can be regulated by adjusting initial tension in the spring.
- a so-called twin screen is shown diagrammatically in Fig. 4.
- a central tube 32, on which a double shade is wound, is present. This is indicated by 33 and 34.
- Shade 33 extends upwards and is immovably fastened to the frame construction 2, like the screens 11 and 12.
- Shade 34 is provided with a weighted end, indicated by 35, which end is free, i.e. if desired moves upwards and downwards by way of a guide, by gravity.
- Tube 32 can be put in the place of tube 9 or 10. The same effect can be obtained in this way.
